Data Matrix

Morpheus Data Matrix provides high-frequency, TEE-verified price feeds synchronized directly to Neo N3 mainnet. These feeds are designed for synchronous consumption by DeFi protocols, lending platforms, algorithmic strategies, and FX / commodity aware contracts.

Operational Architecture

Unlike the request-callback Oracle model, Datafeeds are pre-synchronized state. They operate on an automated operator pipeline:

1. Prover network nodes fetch multi-source quotes inside the TEE.
2. Price normalization and aggregation occur in hardware-protected memory.
3. The TEE signs the consolidated update.
4. The Relayer pushes the update to the on-chain MorpheusDataFeed registry.

Supported Assets

Data Storage Format

All prices are stored as scaled USD integers with a global precision of 1 USD = 1,000,000 units.

• A price of $12.50 is stored as 12500000.
• A price of $65,000.00 is stored as 65000000000.
• A price of $0.002437 is stored as 2437, which is enough to represent low-priced assets such as FLM directly.
• The 0.1% sync threshold is evaluated against the quantized on-chain integer value. With the global 1e6 scale, the standard pair list can use direct pair names such as FLM-USD and JPY-USD instead of basket names.

Canonical Pair Meanings

Contracts and users should use the pair names exactly as written below. Under the global 1e6 precision model, canonical identifiers use the direct asset names such as FLM-USD and JPY-USD.

Contract Integration

Neo N3 (C#)

Use the contract hash 0x03013f49c42a14546c8bbe58f9d434c3517fccab or resolve the NeoNS alias pricefeed.morpheus.neo to the same script hash.

// Read the latest verified price from contract storage
public static void CheckLiquidation() {
    object[] record = (object[])Contract.Call(
        DataFeedHash,
        "getLatest",
        CallFlags.ReadOnly,
        "TWELVEDATA:NEO-USD"
    );
    
    BigInteger priceUnits = (BigInteger)record[2];
    BigInteger lastUpdate = (BigInteger)record[3];
    
    // Process logic...
}

Neo X (Solidity)

Neo X contract publication is still pending. The reference interface below shows the intended read shape once the live registry is published.

// IMorpheusDataFeedX interface
function checkPrice(string memory pair) public view returns (int256) {
    (int256 price, uint256 timestamp) = dataFeed.latestPrice(pair);
    require(block.timestamp - timestamp < 3600, "Price too stale");
    return price;
}
